In order to reduce the evaporation temperature at the heated evaporation surface as far as possible the pressure incl. the hydrostatic pressure due to the liquid product itself should be minimized. The solution is a thin film of the liquid product on the inner side of a vertical evaporation pipe which is generated by a rotating wiper system.
Evaporation efficiency. A two-effect falling-film evaporator with thermocompressor requires about 0.32 kg of steam to evaporate 1 kg of water, and a five-effect evaporator requires 0.09 kg of steam. Without the thermocompressor, the specific steam consumption would be approx. 0.55 and 0.2 kg per kg of water evaporation respectively.
Falling Film Evaporators . In falling film evaporators, liquid and vapors flow downwards in parallel flow. The liquid to be concentrated is preheated to boiling temperature. An even thin film enters the heating tubes via a distribution device in the head of the evaporator, flows downward at boiling temperature, and is partially evaporated.

Send Inquiry Now! The Applications of Rotary Film Evaporator. The rotary evaporator is simply a chemical technique used in the efficient separation of liquids through the gentle separation of samples by evaporating solvents under a vacuum. This method is mostly preferred over other techniques as it is more efficient in getting pure solutions after the separation process.
